\subsection{{\tt{randmat}}: Random Number Generation\label{s:toys-rng}}

This module fills a matrix with pseudo-random integers.

{\inputspec}

\begin{description}
\item[{\tt{nrows, ncols}}:]
	the number of rows and columns in the output matrix.
\item[{\tt{s}}:]
	the random number generation seed.
\end{description}

{\outputspec}

\begin{description}
\item[{\tt{matrix}}:]
	an integer matrix filled with random values.
\end{description}

If possible,
the values produced should depend only on the size of the matrix and the seed,
\emph{not} on the number of processors or threads used.
